Struct CommandOutput 

pub struct CommandOutput {
    pub status: String,
    pub rendered: Option<String>,
}

Output of running one SQL statement through the engine.

Two fields:

• status is the short human-readable confirmation line every caller wants (“INSERT Statement executed.”, “3 rows updated.”, “BEGIN”, etc.).
• rendered is the pre-formatted prettytable rendering of a SELECT’s result rows. Populated only for SELECT statements; None for every other statement type. The REPL prints this above the status line so users see both the rows and the confirmation; SDK / FFI / MCP callers ignore it and reach for the typed-row APIs (Connection::prepare → Statement::query → Rows) when they want row data instead.

Splitting the two means process_command_with_render can return everything the REPL needs without writing to stdout itself — historically process_command would print!() the rendered table directly, which corrupted any non-REPL stdout channel (the MCP server’s JSON-RPC wire, structured loggers piping engine output, …).

Fields

status: String

rendered: Option<String>
